CAR-COUPLING.

PECIFICATION forming part of Letters Patent No. 345,498, dated July 13, 1886.

Application filed March 1?, 1836.

To aZZ whom it may concern:

Be it known that I, J AOKSON B. GARRETT, a eitizen of the United States, residing at Mc- Gregor, in the county of McLennan and Stateof Texas, have invented new and useful Improvements in Car-Couplngs, of which the following is a specifieation.

My invention relates to certain improvements in oar-couplings whereby an o'rdinary draW-head provided with the usual pin-andlink coupling can be readily and cheaply adapted for use as an automatic coupling.

The invention consists in the combination, with a slotted draw-head and a coupling-pin swinging therein and provided with pivotal supports or trunnions, of a vertically-projecting and axially-rotat-able guide loop or staple arranged on each side of the pin slot and adapted to hold the pin frombeing jolted out of the draw-head,and to permitits withdrawal and replacernent when necessary.

My invention also consists in the construction and combination of parts in an automatic carcoup1ing,as hereinafter more fully setforth.

In the annexed drawings,i1lustrating the in- Vention, Figure 1 is a plan of my improved car coupling. Fig. 2 is a longitudinal section of the same. Fig. 3 is a view of one of the draw-heads with coupling-pin removed. Fig. 4 represents the coupling-pin and its guides detached.

Referring to the drawings, the numeral 1 designates a draw-head having a longitudinal recess, 2, with a beveled month, 3, leading thereto. The lower part of the -recess 2 is formed with an inclined or beveled depression, 4, .to permit a swinging movement of the pivoted coupling-pin, and at the forward end of this depression is a shoulder, 5,that1imits the forward movement of the pin and forms an abutment for supporting its lower end.

In the upper part of the draw-head,at its forward end, is a slot, 6, formed by elongating the ordinary upper pin-hole. This slotG is intersected at the top of the draw-head by shallow transverse grooves or depressions 7. that serve as bearings for the trunnions 8 of the couplingpin 9, which is thus adapted to swing within the draw-head. The forward and rear ends of the slot 6*are beveled, as shown, to allow Serial No. 195,714. (No model.)

the pin to swing back when pressed against by the entering link 10, and ashonlder or abutment, 12, is formed at the bottom of the forward inclined end of said slot, immediately above the shoulder or abutment 5, to serve therewith as'a bearing for the forward side of the pin When it is in a vertical position. A On each side of the slot 6 is a movable in guide or stop, 13, consisting of a staple having along arm inserted in the top of the draw-head and turning on its aXis, and a short arm nearly touching the top of the draw-head,but adapted to clear the trunnions 8 as the staple or guide is turned. It will be observed that the grooves 7 are of such depth as that when the pin 9 is in positiou its trunnions 8 are approximately fiush with the top of the draw-head, and therefore offer no obstructon to the adjustment of the stops or guides 13. By turning these guides outward on their long or pivoted arms their short arms will clear the grooves 7 and trunnions 8,and so permit the pin 9 to be removed and replaced without difficulty. After the coupling-pin has been placed in position,with its trunnions 8 resting in the grooves 7, the guides 13 will be turned on their pivots so as to cover or straddle the trunnions, and thus prevent the pin being jolted out of the drawhead.

In 'attaching themovable or pivoted guides 13 it is preferable to provde their long arms with a series of screw-threads, by which they can be readily engaged in suitable orifices formed in the top of the draw-heads. This method of attachment permits a vertical adjnstment of the guides, by which their short arms can be made to approach the surface of the drawhead more or less nearly.

In the upper end of the coupling-pn is an eye, 14, for attachment of a Chain, cord, or lever, by which said pin can be raised either from the sides or top of the car without the risk of inj ury incident to passing between the cars in uncoupling.

It will be observed that the pivoted staples 13 serve as stops to retain the pin 9 within the draw-head, and also as guides for the pintrunnions 8 when the pin is elevated in the act of disengaging it from the link.

The coupling of the cars is efl'ected automatically by reason of tihe entering link foro ing the lower end of the swinging pin back- Ward unbil ib elenrs the end of the link and falls into engagemonb thereWit-h. Should the draW-heads be ofslightly-difi'erent heights,the beveied months 3 will perniib the link to as sume the propor pesition for seenring and innintaining engageinent with the eonplingpins.

It will be seen that; draW-hends provided With the ordinai'y pin-and-link conpling can be readily :Ldnpted to myinvention by Simply eiongating the upper pin-hele to converta it into a slot hzwing beveied ends,and then providing the transverse grooves 7 for the pintrnnnions and the orifices for reeeiving the pivotal ends of the pin-gnides. W'hen the link and pins are engaged and the cars in motion, the dmf is distributed on the shoniders 5 :ind 12, so as to nvoid nndue stmin on the pins, and in case of injnry or brenknge the pin can be readiiy detached and repineed by Simply tnrning the guides 13 to one side,and then retnrning them to their normal position When the pin has been piaeed in the drawhend.

Huving bhns deseribed my inventvion, What I clnini is- 1. Ehe combination, With a slobbed drawhead and a coupling-pin swinging therein and provided With pivotal trunnions, of two VertiealIy-projeeting and axialiy-rotatable loops arranged,respeetive1y,ab opposite sides of the pinslotfio serve as a guide for the trunnions of the pin in the rising and falling movements of the Iatber, substantially as deseribed.

2. The combination of a draW-head having recess 2, provided with inelined depression 4, and a slot, 6,11aving beveied ends, the coupling-pin 9, swinging in the slot) G, and having trnnnions 8,supported in grooves 7, that interseet said slot), and the movable guides 13, ar ranged ou opposite sides of said slot, said gnides being each provided With a Iong nrm having zi screW-thrended end insertod in the top of the drawhead and a short arm adapted 'L0 Clear the pin-t-rnnnions in the net of adjusbing said gnides, substantially as dcseribed.

In testimony Whereof I ni'fix my signabnre in presenee of two WEDGSSOS.
